Abstract: A paint spray booth (10) has a spray chamber (11), an air make-up unit (15), and an air exhaust system with an exhaust air fan (26) and an exhaust damper (25). The booth has a pressure transducer (29) that senses the pressure of air both inside and outside the booth and which transmits control signals indicative of sensed changes in the differential air pressure to motors that drive the exhaust fan or the exhaust damper. In this manner the exhaust air flow rate is adjusted to compensate for changes in the differential air pressure.
Abstract: A method and apparatus (10) are disclosed for deheading shrimp. The apparatus has grasping means (18) for grasping shrimp positioned upon a support plate (17) and rotating the shrimp to an upright position adjacent a deheading station (14). The deheading station has a pinch block (19) having an elongated edge (46) and a pinch plate (20) which is moved closely past the pinch block. The body of the shrimp is pulled from the head as the shrimp is pinched between the pinch block and the moving pinch plate.
Abstract: Shrimp are conveyed in upright orientation upon a pair of spaced rails that revolve in upright planes and which strike bumpers. The shrimp may be size sorted by orienting the rails such that their spacing changes. The shrimp are deheaded by conveying then to a deheader that has a pinch finger that swings by a pinch block.
